VAPOR-BURNING LAMP.

SPECIFICATION forming part of Letters Patent No. 767,726, dated August 16, 1904:. Application filed February 13, 1904. Serial No. 193,394. (No model.)

To all whom it may concern:

Be it known that I, RICHARD WV. ZIERLEIN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Vapor- Burning Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in vapor-burning lamps; and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is an elevation of a lamp, showing my invention applied there.

to. Fig. 2 is an enlarged longitudinal section of the generator and mixing-chamber. Fig. 3 is a transverse vertical section on line 3 3 of Fig. 2. Fig. 1 is a perspective of the tip of the generator. Fig. 5 is a perspective of the mixing-chamber, and Fig. 6 is a transverse section on line 6 6 of Fig. 2.

The object of my invention is to provide the conventional vapor-burning lamp with a sensitive gas-generator capable of converting the liquid hydrocarbon into vapor by the simple 'application of a burning match to the outer walls thereof.

Afurther object is to provide suitable centering devices for such generator, so that the discharge of the vapors therefrom shall always be in a line parallel to the axis of the mixing-chamber.

A further object is to equip the lamp with other details,whose advantages will be readily apparent from a description of the invention, which is as follows:'

Referring to the drawings, 1 represents the container for the liquid hydrocarbon, (gasolene,) from which it is forced under atmospheric pressure through the tube 2 into the passage 3 of the burner wasting 4:, thence through the passage of the arm 5, leading to the valve-casing 6. Mounted in the valvecasing 6 and passing through a stuffing-box 7 thereof is the screw-threaded section 8 of the stem of a needle-valve 8, the latter being loosely enveloped by a wire tube 9, extending wire tube 9, immediately carried by the easing 6, is enveloped by a casing 11, packed with wire-gauze 12, the gauze serving to receive and absorb a portion of the stream of liquid hydrocarbon rushing into the tubing 9 from the branch 5, and thus serving as a retarder of a flow which would otherwise be too rapid to effect the results desired under the present construction. The casing 11 is provided with a polygonal head 11, by which the part 11 can be screwed directly to the valve-casing 6. Mounted loosely on a section of tubing 13,

projecting from a casting 14 at the intake end of the branch 5 of the lamp-frame, is a tubular mixing-chamber 15, whose free end is screw-threaded and by rotating the same about the tubing 13 may be coupled to the screw=threaded portion of the tip 10, as

clearly apparent from Fig. 2. The end of the'pipe 15, adjacent to its junction with the tip 10, is provided with a radially-disposed shunt or section 15, which serves the purpose of taking in the air induced by the discharge of the vapors through the tip 10, the air and vapors thus mixed passing on,as indicated by the arrows, down the branch 5 and unto the burner carrying the mantle M. The main valve V, by which the feed is directly controlled, is mounted on the branch 5. This is on all lamps, and no novelty is claimed therefor.

Those features of the lamp as are not herein either generally or specifically referred to are old or do not come within the contemplation of my invention. It is not to be inferred that the relative disposition of the generator that is, the valve '8 audits enveloping wire tube 9-above the mantle M is new. The disposition of the parts is well known; but the construction of the present generator, which makes it possible to convert the liquid into vapor by the simple application of a burning match, is considered novel. This novelty resides-in the use of the very small wire tube 9 for enveloping the stem 8 of the needlevalve.

Again, by mounting the mixingchamber as indicated it can be coupled to the tip 10 by simple screwing, the valve 8 being thus centered or directed along the axis of the mixingchamber insuring a direct and positive flow of the mixture to the main burner.

In operating the lamp the main valve V and valve 8 are first forced to a closed position. Then a lighted match is held against the walls of the wire tubing 9 and the valve-8 is opened. Then the main valve V is opened, the hydrocarbon under pressure partially being taken up by the retarding-chamber 11 and part rushing past the heated walls of the tubing 9, Where it is ii'nmediately converted into vapor, the latter mixing with the air in the mixing-chamber, the two thence flowing on together into the main burner, where they can be ignited by a match, as obvious.

I may naturally depart from the details of construction here shown without affecting the nature or spirit of my invention.

The detachable mixing-chamber 15 obviously will avoid side drafts, so that the mixture of vapor and air is always substantially uniform.

Having described my invention, what I claim is-' 1. In a vapor burning lamp, a suitable burner, a generator disposed across the same and composed of a suitable needle-valve, and a wire tube loosely enveloping said valve, and a retarder-casing enveloping the wire tube and communicating with the source of hydrocarbon-supply, substantially as set forth.

2. In a vapor-burning lamp, a valve-casing, a needle-valve carried thereby, an enveloping wire tube therefor, a tip at the discharge end of said tube, a retarder-casing enveloping the wire tube and communicating with the source of hydrocarbonsupply, a detachable mixingchamber composed of a tube and radially-disposed shunt adabted to be coupled to said tip, and a pipe-section or tubing for supporting the opposite end of the mixing-chamber, substantially as set forth.

3. A vapor-burning lamp, comprising a suitable container, a burner mounted over the same, suitable pipes for conducting the hydrocarbon from the container to the burner, a generator disposed across the flame issuing from the burner, said generator comprising a needle-valve stem and a wire tube loosely enveloping the same, a valve-casing mounted in the path of one of the pipes for supporting one end of the needle-valve and wire tube enveloping the same, a retarder 1 casing surrounding a section of the length of the wire tube coupled directly to the valve-casing and communicating with the source of hydrocarbon-supply, a tube-section mounted opposite the valve-casing on one of the pipes or branches leading to the main burner, a sliding and rotatable mixing-chamber loosely fitting over said tube-section, a screw-threaded perforated tip at the adjacent end of the wire tube to which said mixing-chamber can be coupled, thereby accurately centering the generator to the axis of the mixing-chamber, the parts operating substantially as, and for the purpose set forth.

4C. In a vapor-burning lamp, a suitable burner, a generator disposed across the same, and composed of a needle-valve and a wire tube loosely enveloping the same, a retardercasing enveloping the Wire tube and communicating with the source of hydrocarbon-supply, a tip on said wire tube, and a sliding and rotatable mixing-chamber mounted at a point opposite said tip and adapted to be coupled thereto, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

RICHARD W. ZIERLEIN.
